Jacksonville's defense turned in its best performance in two months. Fred Taylor topped it with the longest run in team history. Together, they helped the Jaguars move a step closer to securing an AFC playoff berth. Taylor ran for 132 yards and a touchdown; the defense looked like its old self; and the Jaguars beat the Carolina Panthers 37-6 on Sunday. Jacksonville (9-4) harassed Vinny Testaverde, stuffed DeShaun Foster and locked down Steve Smith - the defense's most complete game since consecutive wins at Denver and Kansas City early in the season.
